Pit-type steam blackening furnace, oxidation furnace, hair blue furnace, powder metallurgy environmental blackening furnace, water vapor hair orchid furnace,pit steam blackening furnace

Pit-type steam blackening furnace, oxidation furnace, hair blue furnace, powder metallurgy environmental blackening furnace, water vapor hair orchid furnace,pit steam blackening furnace energy-precision temperature control system operating cycle furnace, furnace tank through the water vapor, for sintering of powder metallurgy iron-based products for surface treatment, but also can be used as mechanical parts black surface treatment. The resistance furnace by the furnace, lifting mechanism, stirring fans, steam boilers, temperature control systems and other components.

The full name of the black pit furnace black furnace may be called vapor steam furnace black, blue stove, bluing furnace, steam bluing furnace, steam heaters.

Pit-type steam blackening furnace, oxidation furnace, hair blue furnace, powder metallurgy environmental blackening furnace, water vapor hair orchid furnace,pit steam blackening furnace is circular, steel plate, steel welded into the furnace shell and lining, heating elements with ultra lightweight refractory bricks, insulation materials are placed on dormant silk brick hearth with steel welded into of the vessel, the lid is equipped with loop mixing fan.

Black furnace is energy-efficient furnace operation precision temperature control cycle. Microcomputer program precision temperature control cabinet multi-zone temperature control, temperature control system consists of a thermocouple, digital intelligent PID regulator and a thyristor to form a closed loop control system, automatic precise temperature control. Vacuum fan speed hot air circulation, steam black furnace atmosphere, temperature is extremely uniform. For compressor rotor, stator, silicon, high-speed steel cutting tools, tooling fixtures, metallurgy and other vapor blackening purposes. Black stove has a steam inlet pipe, water vapor enters the furnace, furnace black at a specific pressure environment dense oxide film of iron tetroxide (this process is the industry commonly known as "black" and the work piece "bluing" "bluing"). Prevent the workpiece play rust, corrosion and other effects in daily use environments.

Black furnace and its configuration functions:

1. Furnace using 1Cr18Ni9Ti stainless steel.

2. Insulation material made of high quality aluminum silicate cotton.

3. The use of electric heating alloy ribbon or wire, easy maintenance.

4. Unique hot air circulation system, so that indoor temperature distribution.

5. Use water jacket cooling fan and lid.

6. All kinds of protective atmosphere can manually adjust the flow according to process requirements.

7. black Furnace control using PID expert with no overshoot algorithm import smart meters, through zero trigger power modules to control the heating power. Up and down 2 to 3 zone temperature control, so that the furnace temperature is more uniform.

8. with a meter, you can measure power consumption.

9. With over-temperature alarm system, when the furnace temperature exceeds the set range can audible alarm signal, and cut off the heating power.

10. The independent control cabinet can conveniently control, centralized control may also be in the control room.

11. Since the black furnace temperature uniformity, there is a certain pressure steam in the furnace, the oxide film products, good compactness, uniform hardness.
